Published Reading between the cracks: Artificial intelligence can identify patterns in surface cracking to assess damage in reinforced concrete structures



Researchers are trying to make the process more efficient and definitive by using artificial intelligence, combined with a classic mathematical method for quantifying web-like networks, to determine how damaged a concrete structure is, based solely on its pattern of cracking.
Published New priming method improves battery life, efficiency



Engineers have developed a readily scalable method to optimize a silicon anode priming method that increases lithium-ion battery performance by 22% to 44%.
Published With new experimental method, researchers probe spin structure in 2D materials for first time



In the study, a team of researchers describe what they believe to be the first measurement showing direct interaction between electrons spinning in a 2D material and photons coming from microwave radiation.
Published Extracting the best flavor from coffee



Researchers explore the role of uneven coffee extraction using a simple mathematical model. They split the coffee into two regions to examine whether uneven flow does in fact make weaker espresso. One of the regions in the model system hosted more tightly packed coffee than the other, which caused an initial disparity in flow resistance. The extraction of coffee decreased the flow resistance further. Understanding the origin of uneven extraction and avoiding or preventing it could enable better brews and substantial financial savings by using coffee more efficiently.
Published Symmetric graphene quantum dots for future qubits



Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism -- one of the necessary criteria for quantum computing.
Published Unraveling the mathematics behind wiggly worm knots



Researchers wanted to understand precisely how blackworms execute tangling and ultrafast untangling movements for a myriad of biological functions. They researched the topology of the tangles. Their research could inform the design of fiber-like, shapeshifting robotics that self-assemble and move in ways that are fast and reversible.
Published Researchers design battery prototype with fiber-shaped cathode



In a new study, researchers made a cathode, or the positive end of a battery, in the shape of a thread-like fiber. The researchers were then able to use the fiber to create a zinc-ion battery prototype that could power a wrist watch.
Published ChatGPT is still no match for humans when it comes to accounting



ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation



Organic solar cells show great promise for clean energy applications. However, photovoltaic modules made from organic semiconductors do not maintain their efficiency for long enough under sunlight for real world applications. Scientists have now revealed an important reason why organic solar cells rapidly degrade under operation. This new insight will drive the design of more stale materials for organic semiconductor-based photovoltaics, thus enabling cheap and renewable electricity generation.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers



In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Graphene 'tattoo' treats cardiac arrhythmia with light



Researchers have developed the first cardiac implant made from graphene, a two-dimensional super material with ultra-strong, lightweight and conductive properties. Similar in appearance to a child's temporary tattoo, the new graphene 'tattoo' implant is thinner than a single strand of hair yet still functions like a classical pacemaker.
Published Physicists discover transformable nano-scale electronic devices



The nano-scale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But physicists have reported the discovery of nano-scale devices that can transform into many different shapes and sizes even though they exist in solid states.
Published Wonder material graphene claims yet another superlative



Researchers report record-high magnetoresistance that appears in graphene under ambient conditions.
Published Fully recyclable printed electronics ditch toxic chemicals for water



Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Discovery of ferroelectricity in an elementary substance



Researchers have discovered a new single-element ferroelectric material that alters the current understanding of conventional ferroelectric materials and has future applications in data storage devices.
Published Strong ultralight material could aid energy storage, carbon capture



Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.
Published Is it COVID-19 or the flu? New sensor could tell you in 10 seconds


Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
Published Nanophysics: The right twist


Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published Graphene grows -- and we can see it


Graphene is the strongest of all materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010. Yet, many properties of the material and its cousins are still poorly understood -- for the simple reason that the atoms they are made up of are very difficult to observe.
Published New simulation reveals secrets of exotic form of electrons called polarons


Conditions mapped for the first time of polaron characteristics in 2D materials. TACC's Frontera supercomputer generated quantum mechanical calculations on hexagonal boron nitride system of 30,000 atoms.
